honestly?! can you beat that? nope But this app sure is nice, not sure how it compares to apple's speed test app.TESTED ON WIFI IN PICTURE
The interface "gui" is very easy. Just a simple "Start Speedtest" button. One tap and 10 seconds later its done with the report. Yes this is a very short review but not much to say really... Its a 1 button only program!

yea it's just a rumor... because they did put a limit on the blackberry and PDA devices that are "legally" capable of tethering... Just got through reading the whole AT&T agreement thingy and it said nothing about data limits for the iPhone... but it did mention that there are limits to be determined by AT&T if they feel their service is being abused... they also mention what you can and cannot do with your iphone (for example tether)...

personally i tethered my 1st gen and hit over 5GB in a month and never got charged extra for it...

I'd be interested in reading my contract terms a bit better to see if any limit was mentioned as part of my unlimited data plan. I understand charging an abusive user (tethering) but between the AppStore, maps services, websites and downloading files/email I've surpassed 4gbs (didn't get to 5gb).
